Note 1: The characters to the left disappear above 100 Hz. (Ex: 120 Hz is )
Note 2: You can switch between % and A (ampere)/V (volt), using the parameter  (current/voltage unit
selection).
Note 3: The input (DC) voltage displayed is 1/ 2 times as large as the rectified d.c. input voltage. In case of
1ph-120, displayed value is 1/2 times in addition.
Note 4: If  = 2 (Logic input): VI bar is activated depend on VI terminal ON/OFF.
8
If  = 0, 1 or 3 (Voltage/current input): VI bar is always OFF.
Note 5: If  = 0 (Logic output): Out bar is activated depend on OUT terminal ON/OFF.
If  = 1 (Pulse train output): OUT bar is always OFF.
Note 6: Past trip records are displayed in the following sequence: 1 (latest trip record) 234 (oldest trip
record). If no trip occurred in the past, the message "" will be displayed. Details on past trip
record 1, 2, 3 or 4 can be displayed by pressing the center of the setting dial when past trip 1, 2, 3 or 4 is
displayed. Refer to section 8.2.2 for details.
Note 7: Parts replacement alarm is displayed based on the value calculated from the annual average ambient
temperature specified using , the ON time of the inverter, the operating time of the motor and the
output current ( load factor). Use this alarm as a guide only, since it is based on a rough estimation.
Note 8: The cumulative operation time increments only when the machine is in operation.
Note 9: If there is no trip record, nerr is displayed.
Note 10: Of the items displayed on the monitor, the reference values of items expressed in percent are listed below.

MODE
The current monitored is displayed. The unit can be switched to A
(amperes).
The voltage displayed is the voltage determined by converting the voltage
measured in the DC section into an AC voltage. The reference value
(100% value) is 400 volts for 400V models. The unit can be switched to V
(volts).
